Abstract:Seismic imaging is generally a technique to fi gure out the subsurface structure or physical properties of subsurface media. It is often considered the same as seismic migration in refl ection seismic. Migration has been the means of collapsing diffraction events to points, moving migrating refl ection events to the proper locations to obtain a true image of subsurface structures. Over the years, the technique of migration has evolved. It started from NMO normal move out for the horizontally layered structure,… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
